# / ml (SlashML · slashml.ai) — Complete Self-Contained API & Benchmark Reference (`llms-full.txt`)

This document is designed for both human engineers and autonomous coding agents (ChatGPT, Claude, Perplexity, Cursor, Claude Code, Codex). Every API section below is **100% self-contained** with its full URL, authentication headers, request schema, response schema, and copy-pasteable runnable code.

- **Brand & Package Names:** `/ ml` (pronounced and searched as **SlashML**), website `https://slashml.ai`, Python SDK `pip install slashml`, TypeScript/MCP CLI `npx @slashml/memory`, MCP skill `ml-memory`.
- **Base URL:** `https://api.slashml.ai`
